SPECIFICATION forming part of Letters Patent No. 308,810, dated December2, 188

Application filed October 26, 1883.

T 0 all whom it may concern: 7

Be it known that we, CHARLES J. SNYDER and ZAVALA Lnwrs, citizens of theUnited States, residing at Topeka, in the county of Shawnee and State ofKansas, have invented certain new and useful Improvements in Rail-Splicing Safety-Locks, of which the following is a specification,reference being had therein to the accompanying drawings.

Our invention relates to improvements in railsplicing safety-locks; andit consists in the novel construction and combination of the severalparts, as will be hereinafter described, and pointed out in the claim.

In the drawings, Figure l is a side view of our improved joint. Fig. 2is a longitudinal section on line :0 as, Fig. 1. Fig. 3 is a detail Viewof the bolt; and Figs. 4C, 5, 6, and 7 are detail views showing theboxing, packing, and-locking-plate, all of which will be de scribed.

The rail A is provided with perforations a near its end, and fishplatesB B are arranged on opposite sides of the rail, and provided withopenings b, registering with the openings at in the rail. These openingsb are formed with eccentric extensions or notches b to receive the lugsor cars on the boxing, presently. described. The bolt 0 is providedwith, a head, 0, and on it near the said head we form the wings c, whichfit the notches I) in the bolt-hole b, and prevent the bolt fromturning, as will be readily understood. The boxing D is composed ofbase-plate d'and flange or rim d. An opening, 01*, is formed through thebase-plate to permit the passage of the bolt 0. Ears or lugs c e areprojected outward, on opposite sides of the opening a, and fit into thenotches b of opening I), and keep the boxing from revolving in theoperation of the device. Recesses e c are formed in the upper and loweredges of theflange d, to receive the arms of the locking-plate, and lugsc c are projected forward from the opposite sides of said flange, asshown. These lugs are turned down against the locking-plate and securethe same in place in the boxing in the operation of the device. Thepacking ring E is preferably made of rubber, and is conformed to theboxing D, in which it is placed. Its opening E registers with the(ModeL) bolt-opening in the rail, fish-plates, and boxing, as readilyseen in Fig. 2. The lockingboxing is made in an oval or other eccentricshape, so that the locking-plate will not re volve when placed thereinin the application of the device. The nut G isof ordinary construction,and in operation is turned on the outer end of the bolt down against thelocking-plate, thearms of which are then turned down against the facesof the nut, and the same is securely locked. The unlocking of the nut isreadily accomplished by the rebending of the arms in a manner that willbe apparent.

lVhere so desired, the packing-ring may be dispensed with; but we preferits use for the following reasons:

It is found in practice that the jarring or vibration caused by therunning of cars over the joints in railroad-rails tends not only toloosen the nuts, but, where bolts are rigidly fitted or secured, todamage the bolts themselves, so that bolts having nuts securely lockedwould be much less durable, unless packing be used to soften or deadenor counteract the effect of the constant vibration or jarring.

It is obvious that where so desired, instead of using the notches in thebolt-opening and wings on the bolt and lugs c on the lockingplate, theboxing could be keyed on the bolt by the well-known feather and keyfastening, or in various other ways. \Ve prefer, however, theconstruction shown and described, as thereby a firm fastening of theparts is had and a simple, easily-operated device is provided.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is

The combination, with the bolt 0, the nut ICO outward and resting in thenotches e e, and turned up against the nut, to permit the strain of thenut to fall upon the elastic block, substantially as set forth.

In testimony whereof we affix our signatures in presence of twowitnesses.
